I have CAT7 from my WRT wifi router to a RJ45 wall plate on the main level, which is connecting to a wall plate on the 2nd level via CAT7. I tried using a 8-port switch (unmanaged) but I don't get a signal. However, when i remove the switch and connect a device directly to the wall plate i get a ethernet signal and connection. I don't understand what could be the issue.
